Speaking to the media for the first time since the Giants disclosed in early June that he had lymphoma, Gettleman said Friday he’s had four rounds of chemotherapy and will need another three more to complete his treatment.

The 67-year-old Gettleman returned to the Giants earlier this year to replace the fired Jerry Reese. He says he is feeling better than expected, but is limited in what he can do.

”I feel really good and sometimes I feel like I am apologizing for that,” Gettleman said. ”But you know my energy is good. I don’t mind telling you chemo ain’t fun. There has been a couple of days where `whef,’ it rocks your world. Now that I am going through it … my gosh, it’s not fun.”

Gettleman said when he gets treatment he has to stay in the hospital for three or four days. When he is in the office, he works roughly from 10 a.m. to 7 or 7:30 p.m.

The treatments have weakened Gettleman’s immune system and he said he can’t have much contract with people. He has to watch training camp practices from a distance in the shade, eat alone and can’t fly on airplanes. He is going to miss the Giants’ workouts in Detroit with the Lions next month.

Gettleman also predicted he would return to his job full-time this season. He also plans to take part in the upcoming contract talks for star receiver Odell Beckham Jr.

Gettleman said it was weird hearing from his physician, Dr. Andre Goy, that he was in remission.

”Just all of a sudden you go from, within a five-week period I’m told I’ve got aggressive lymphoma, and in five weeks, he said everything is going to be OK. That’s a quick turnaround,” said Gettleman, who served as the Carolina Panthers’ general manager from 2013-16.

Gettleman spoke to the Giants players after they reported to training camp Wednesday, saying that he told them two things.

The first was about the importance of being a team, and was highlighted by a recent comment from New York Islanders general manager Lou Lamoriello after center John Tavares signed as a free agent with Toronto earlier this month.

”Lou made a great statement, which I believe in and subscribe to, in that individuals win games and teams win championships,” Gettleman said.

The other point Gettleman stressed was that the players have earned the right to be in training camp and now it was up to them to make the 53-man roster and the 47-man dress squad for games.

Gettleman also showed he has not lost his sense of humor, noting that he told the players it feels different being bald. The chemo caused his hair to fall out.

”It’s weird now getting up with a head of hair and looking at that face,” Gettleman said.

”Life is precious,” he said. ”I don’t care what it is, you just can’t not appreciate how important people are and how, really, we’re in the people business. At the end of the day, it’s not about how much money you make. It really isn’t, it doesn’t mean anything. It’s really about what you do with your gifts, and family is our true legacy.”

Kansas City Chiefs coach Andy Reid arrived Sunday on the campus of Missouri Western State University to start his 20th season as an NFL head coach, yet finds himself energized by what’s new on his football team for 2018.

”There’s more new I would say on both sides of the ball,” Reid said. ”Some of the old guys that have been here aren’t here.”

The team lost several veterans during the offseason, trading quarterback Alex Smith to Washington and parting ways with longtime linebackers Derrick Johnson and Tamba Hali among other moves.

The offseason changes result in a team navigating through its most significant turnover since Reid’s 2013 arrival in Kansas City.

”Whether it’s the quarterback position, inside linebacker position, outside linebacker position, you’re missing a few of those guys and you have new guys coming in that you have an opportunity to see perform,” Reid said. ”That’s exciting to me, I’m looking forward to that.”

The biggest change comes at quarterback with Smith giving way to Patrick Mahomes, the No. 10 overall selection in last year’s draft. Smith won 50 regular-season games as the team’s starter since 2013.

”Alex was phenomenal, he’s going to continue to be phenomenal for the Redskins and we feel very lucky to have Pat, to be able to step up and watch him grow here,” Reid said. ”Let’s see how he does. He can’t be in any better place, man, than with the Kansas City Chiefs and I know he’s fired up about that.”

Mahomes arrived in camp Sunday along with the team’s other quarterbacks and with coaches, rookies and select veterans. A three-day minicamp starts on Monday before the full squad checks in on July 25. The first full team practice kicks off July 26.

The 22-year-old faces no competition for the starting quarterback job. The team acquired veteran Chad Henne as his understudy and to serve as a sounding board for Mahomes as he navigates his first full season as a starter. Mahomes hopes to use his time in camp to become a more efficient quarterback.

”I want to make sure I can get in and out of the huddle fast Youth Tracy Walker Jersey , we can make the right checks and just really have a lot of positive plays,” Mahomes said.

”Not necessarily the huge plays but just have positive plays and move the chains. That’s how you have success in the NFL. You keep taking those yards, taking those yards and then when you have guys that can stretch the field you make those plays and those come within the flow of the game.”

With new faces arriving in camp this week, Reid had good news about some of the team’s key players returning from injury.

The coach said he expects only wide receiver De’Anthony Thomas and cornerback Ashton Lampkin possibly starting camp on the sidelines. That means center Mitch Morse, linebacker Dee Ford and running back Spencer Ware, all returning from season-ending injuries a year ago, expect to practice with the team.

”All those guys, everybody else is good,” Reid said. ”Again I just want to see on the field and we’ll kind of monitor as it goes but, yeah, they all should be ready to go.”

The quarterback change and other roster turnover create an array of differing expectations for this Chiefs’ team. Many preseason prognosticators have the Los Angeles Chargers replacing Kansas City atop the AFC West after back-to-back divisional titles.

Reid, however, doesn’t see it that way.

”But the important thing is there is high expectations within the building, within the team,” Reid said. ”They demand that from themselves. You felt that in the OTAs and I expect that to continue. I expect guys to challenge each other, that’s the way you get better. We’ve got great competition that we’re going to play this year starting with the Chargers.”

Yet with many viewing the 2018 season as a transition, if not rebuilding, year for the Chiefs, even Reid acknowledges that this season paves the way for a brighter future under Mahomes.

”We’re striving to win a championship and then to consistently be in a position where we can win a championship as the years go on,” Reid said. ”And it starts again today.”
